Abstract: Monolithic beam-shaping optical systems and methods are disclosed for an optical coherence tomography (OCT) probe that includes a transparent cylindrical housing having asymmetric optical power. The system includes a transparent monolithic body having a folded optical axis and at least one alignment feature that supports the end of an optical fiber adjacent an angled planar end wall. The monolithic body also includes a total-internal reflection surface and a lens surface that define object and image planes. Light from the optical fiber end traverses the optical path, which includes the cylindrical housing residing between the lens surface and the image plane. Either the lens surface by itself or the lens surface and the reflective (eg, TIR) surface in combination are configured to substantially correct for the asymmetric optical power of the cylindrical housing, thereby forming a substantially rotationally symmetric image spot at the image plane.

Abstract: Integrated torque jacket systems and methods for optical coherence tomography are disclosed. The system includes an optical fiber cable having an optical fiber surrounded by an outer jacket. An optical probe is operably attached to the distal end of the optical fiber cable. The optical fiber cable includes either a plurality of low-friction bearings or a spiral member operably attached thereto along its length, thereby defining the integrated torque jacket system. The integrated torque jacket system resides within the flexible guide tube with a close fit that allows for rotation and axial translation of the integrated torque jacket system within the guide tube interior. The integrated torque jacket system serves to transfer torque and axial translation applied at its proximal end to the distal end to rotate and axially translate the optical probe within the guide tube.
